Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Mahavitaran android application 7.50 and prior are affected by account takeover due to improper OTP validation, allows remote attackers to control a users account.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

The Mahavitaran Android application versions 7.50 and prior contains a critical authentication bypass vulnerability where improper OTP (One-Time Password) validation allows remote attackers to take control of user accounts. The OTP validation mechanism fails to properly validate or verify one-time passwords, enabling account takeover without legitimate access.

MitigationImplement proper OTP validation by ensuring OTPs are cryptographically random, tied to specific sessions/users, have appropriate expiration times, rate limiting, and server-side validation that cannot be bypassed. Additionally, implement account lockout policies and multi-factor authentication where possible.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify installed Mahavitaran app version
    On the Android device, go to Settings > Apps > Mahavitaran (or Mahadiscom) and view the version number under App Info, or use adb shell dumpsys package <package_name> to retrieve version details
    Affected if The displayed version is 7.50 or any version lower than 7.50
  2. Confirm the application package name
    Run 'adb shell pm list packages | grep -i mahavitaran' or 'adb shell pm list packages | grep -i mahadiscom' to identify the exact package name of the installed application
    Affected if The package belongs to Mahavitaran or Mahadiscom and the version check above shows <= 7.50
  3. Verify OTP authentication is in use
    Attempt to log into the Mahavitaran application using the OTP-based login flow to confirm the authentication mechanism is active and accessible
    Affected if OTP login is available and the application version is <= 7.50

The environment is affected if the Mahavitaran Android application version 7.50 or lower is installed and OTP-based authentication is enabled.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

Upgrade available Upgrade to a release after 7.50
Interim mitigation

Implement proper OTP validation by ensuring OTPs are cryptographically random, tied to specific sessions/users, have appropriate expiration times, rate limiting, and server-side validation that cannot be bypassed. Additionally, implement account lockout policies and multi-factor authentication where possible.
